Having an issue using this on App Engine

Is there an alternative to multiprocessing?

I'm having the same issue. Any answer?

Same issue here. It's surprising to see so few postings about the use of Firebase on Google Appengine on the internet.

@puruzio @kevinchau This library doesn't work in GAE and they still have no plans to do it. The best you can do is to create/reuse a simple wrapper around the REST api (for the methods you need). The library to generate the tokens works well.

If you are not using the async methods you can workaround the issue by disabling the multiprocessing (that's my case...).

class dummy:
    def close(self):
        pass
    def join(self):
        pass
    def terminate(self):
        pass

class DummyProccessing(ModuleType):
    def __init__(self):
        pass
    @staticmethod
    def Pool(processes):
        return dummy()

sys.modules['firebase.async.process_pool'] = dummy()
sys.modules['multiprocessing'] = DummyProccessing
